It looks like the same problem is present also in Ubuntu 14.04 LTS.

Plaintext passthrough has been broken by design for a very long time, and practically impossible to support.

[Bug 842647] Re: [git] file blocks duplicated at the end of the file
The patch I linked to in comment 10 breaks plaintext passthrough support. The logic around handling plaintext passthrough and the metadata-in-xattrs feature is very delicate in this part of the code. I'd love to deprecate/remove those two "features" in future kernels, as they're rarely used by anyone, but we need a fix that is backportable. I'm going to think this through a little more and I hope to have a new patch this later this evening. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/842647 Title: [git] file blocks duplicated at the end of the file To manage notifications about this bug go to: https://bugs.launchpad.net/ecryptfs/+bug/842647/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 842647] Re: [git] file blocks duplicated at the end of the file
Thanks - I can reproduce this and have tracked down the problem. We're missing an eCryptfs metadata read, in the ecryptfs_getattr() path, after a metadata read in the lookup() path fails. This results in a stat() call returning an incorrect inode size and then subsequent read()'s not adding up to the correct file size. I've started on a fix, but will need a bit more time, as this code is fragile and needs improvements outside of this bug. ** Changed in: ecryptfs-utils (Ubuntu) Status: Confirmed => In Progress ** Also affects: ecryptfs Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/842647 Title: [git] file blocks duplicated at the end of the file To manage notifications about this bug go to: https://bugs.launchpad.net/ecryptfs/+bug/842647/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
